Just noodling around on an auction site and finding that the lenses used for imaging oscilloscope traces seem to have jumped in pricwe point. These used to be a dime a dozen . . .well $50 each. Now I am seeing them at well over $150 and on up to $260 in some cases.
What is up with this? In years past, have been assured they are mediocre at best by knowledgeable forum members here.
Who is paying top dollar for these lenses and why?
